<\/p>\n\nA \u00een\u021belege misterele „fantom\u0103” dulciuri \u00een vinuri seci, aparent \u2013 \u00een lemn butoaie. Dar cum vinul poate fi dulce la gust, \u00een lipsa nivelul de zah\u0103r? S-a dovedit, motivul nu este acolo, \u00een cazul \u00een care se obi\u0219nuia s\u0103 se g\u00e2ndeasc\u0103.<\/p>\n
<\/p>\n
\nCu siguran\u021b\u0103 a\u021bi avut de a degusta vin alb sec, care p\u0103rea un gust, nec\u0103t\u00e2nd la afirma\u021biile vinificatorului este c\u0103 acesta este complet uscat. \u0218i nu E\u0219ti singur \u00een asta. Acest fenomen o lung\u0103 perioad\u0103 de timp f\u0103cea degust\u0103tori \u0432\u0441\u043a\u0438\u0434\u044b\u0432\u0430\u0442\u044c spr\u00e2ncenele \u00een surprindere \u0219i s\u0103 se \u00eendoiasc\u0103 de propriile opinii, care p\u0103rea a fi contrazis de fapte.\n<\/p>\n
\n „Ideea de dulciuri f\u0103r\u0103 zah\u0103r pare a fi un paradox”, spune Axel \u041c\u0430\u0440\u0448\u0430\u043b\u044c de la Universitatea din Bordeaux. La sf\u00e2r\u0219itul zero, el a \u00eenceput un studiu \u00een care aceast\u0103 \u00eentrebare a fost de baz\u0103.<\/p>\n
\nSunt de p\u0103rere c\u0103 etanolul \u0219i glicerina provoac\u0103 un sentiment de dulciuri \u00eentr-un loc uscat vina, dar de cercetare, inclusiv realizat de \u041c\u0430\u0440\u0448\u0430\u043b\u0435\u043c, nu au dat dovad\u0103 de aceast\u0103 afirma\u021bie. S-a dovedit c\u0103 butoaie de stejar au mult mai mult efect de la senza\u021bii gustative de pahar de chardonnay.\n<\/p>\n
\n„Am descoperit o \u00eentreag\u0103 familie de substan\u021be, pe care mai \u00eenainte nu a acordat o aten\u021bie special\u0103. Ei liber se \u00eencadreaz\u0103 \u00een vinul din butoaie de lemn \u0219i dau senza\u021bia de dulciuri din lipsa de zaharuri. \u00cen acest caz, ele sunt de 8000 de ori mai dulce dec\u00e2t zaharoza”.<\/p>\n
\nF\u0103r\u0103 g\u00e2ndire, oamenii de stiinta le-au dat simpl\u0103 de a aminti numele \u043a\u0432\u0435\u0440\u043a\u043e\u0442\u0440\u0438\u0442\u0435\u0440\u043f\u0435\u043d\u043e\u0437\u0438\u0434\u044b (de la lat. Quercus, stejar).

\n „S-a constatat c\u0103 \u00een st\u00eenci de stejar con\u021bine mult mai multe astfel de dulci conexiuni dec\u00e2t stejarul \u0447\u0435\u0440\u0435\u0448\u0447\u0430\u0442\u044b\u0439, prin urmare, mai potrivite pentru obiectivele de vinifica\u021bie”, spune \u041c\u0430\u0440\u0448\u0430\u043b\u044c. <\/p>\n
